An empirical study of the impacts of operating and market conditions on container-port efficiency and benchmarking

Despite the growing amount of research on container-port efficiency and benchmarking, the literature on the subject is yet to provide stable and consistent results across researchers and in relation to dynamic operating and market conditions. In this paper, we formulate a number of operational hypotheses to test the sensitivity of benchmarking results to port market and operating conditions namely production scale, cargo mix, transhipment ratio, operating configurations, and working procedures. A series of data envelopment analysis (DEA) models are used to measure the operational efficiency of 420 container terminal decision-making units from 2004 till 2010. The results show that variations in operating conditions highly impact terminal efficiency and that future work on container-port performance and benchmarking should take into account the structure and mechanisms underpinning the operations of container ports and terminals.     

深海工程装备研发中若干共性水动力学问题

开展深海工程装备研发中水动力学相关项目的研究,不仅能深化对深海环境条件与浮式海洋结构物相互作用规律的认识,进一步丰富和发展深海资源开发的技术手段,而且可有效地缩短与国外在深海开发技术方面的差距,直接为深远海水域重大工程的规划设计、海洋资源开发提供技术指导和服务.本文结合我们近年来在海洋资源开发相关的水动力学方面开展的研究工作和对国内外研究进展的认识,就今后深海工程装备研发中水动力学(主要是水波动力学)可能的发展方向作一简要的评述.

Modeling user adoption of advanced traveler information systems: dynamic evolution and stationary equilibrium

This paper models the growth rate and the saturation market penetration level for advanced traveler information system (ATIS) products/services with heterogeneous drivers. The price of using and the benefit gained from ATIS services are considered two key factors in explaining the growth of adoption of ATIS products. The information benefit is measured as the travel time saving between equipped and unequipped drivers and evaluated by a mixed stochastic and deterministic network equilibrium model. A modified logistic type growth model is adopted to describe the cumulative adoption of ATIS products over years. The final stationary equilibrium level of ATIS market penetration is so determined that the value of the information provided will decline to the point at which no new users will find it advantageous to purchase that service. The endogenous growth and stationary equilibrium model of market penetration of ATIS services is useful for forecasting the growth process and the impacts on the system performance of ATIS.     

土耳其摩托车市场和准入管理制度（1）

土耳其的摩托车市场在近几年发展比较迅猛,目前,土耳其全国的摩托车保有量达到250万辆,每千人拥有30辆摩托车。土耳其由于在地理上靠近欧洲,因此在车辆产品的管理和技术法规方面受欧洲影响很大,与国际惯例相符合的程度也很高。土耳其负责车辆产品市场准入管理的政府主管和批准机关为土耳其工业与贸易部,该机关负责整车产品和零部件的型式批准。

Intrinsic Value and Market Timing of Initial Public Offerings

To avoid debates on the interpretation problem of market-to-book, the residual income model is employed to calculate the intrinsic value and estimate the extent of mis-pricing by market. Using a sample of Chinese listed companies from 1998 to 2003, the empirical evidence supports that equity market mis-pricing plays a significant role in decision making on the initial public offering. Our evidence verifies that the market timing theory can be applied to the analysis of financing behavior of Chinese listed companies, but the long-lasting effect is insignificant.
